Chris Brown and aspiring model Karrueche Tran are still going strong after about five months together, and Tran, 23, made a point of publicly reconfirming the romance via Twitter and Instagram on Monday.

No response -- yet -- from Rihanna, who warred with Tran in early March via Facebook and Twitter. "We Found Love" singer Rihanna seemed to kick off a feud with a March 3 TwitPic that could be interpreted as a racist jab at Tran, who is half-Vietnamese: A bag of rice cakes with gold earrings and black shades, along with the caption, "Ima make u my bitch."

(Source told Us Weekly that Rihanna and abusive ex Brown, who recently collaborated on two remixes together, had been secretly hooking up again for over a year.) Tran retaliated with a reference to the Brad Pitt/Angelina Jolie/Jennifer Aniston love triangle. "I'm Angeline [sic], you're Jen. C'mon you see where Brad is at," she sniped.
